Find out moreManufactured from GRP material, a high-quality unfilled polyester resin with glass fibre reinforcement, this Corodrain A-Type valley trough is a narrow valley trough suitable for use with single lap tiles in restricted applications. This AX30 heavy-duty A-type valley integrates a 35mm sanded strip for the adhesion of mortar and displays resistance to UV light and acid rain with a smooth surface that rejects moss, lichen, and debris build-up.
Applicable for use on roofs with pitches from 22.5° up to 49°, this valley trough can accommodate a maximum difference between two rafter pitches of 10°. It is quick to install alongside interlocking tiles and can also be used with manufactured and natural slate. Its appearance resembles real lead at a reduced price but combines enhanced durability against accidental damage and reduced susceptibility to theft, featuring a 30-year lifespan like that of real lead.
Corodrain valley troughs and gutters demonstrate a high level of compatibility with a wide range of roofing materials, such as natural and man-made slate, clay, and concrete tiles. These lead replacements offer both cost-effectiveness and durability, adhering to the outlined requirements for 'standard' double lap valley troughs as specified in NFRC Technical Bulletin 28.
